Mochine oa Mycobacterium smegmatis G (MbsG), l-lysine monooxygenase e itšetlehileng ka flavin, o ile oa batlisisoa tlas'a maemo a tsitsitseng le a potlakileng a karabelo ho sebelisoa liphello tsa kinetic isotope tsa mantlha le tsa solvent, li-analogue tsa substrate, pH le liphello tsa viscosity ea solvent e le li-probes tsa mechine.Liphetho li fana ka maikutlo a hore l-lysine e tlama pele ho NAD(P)H, e lebisang ho fokotseha ha sekhahla sa phokotso ea flavin.Ho tlama ha l-lysine ha ho na phello ho sekhahla sa oxidation ea flavin, e hlahang ka mohato o le mong ntle le ho ela hloko C4a-hydroperoxyflavin e bohareng.Litlamorao tse tšoanang li ile tsa khethoa ka li-analogues tse 'maloa tsa substrate.Flavin oxidation e na le pH e ikemetseng ha kcat/Km le kred/KD pH profiles tsa NAD(P)H li bonts'a boleng bo le bong ba pKa ba ~6.0, ka ts'ebetso e ntseng e eketseha ha pH e fokotseha.Ha pH e le tlase, enzyme e fetoha e sa kopane, e hlahisa hydrogen peroxide e ngata le superoxide.Phetisetso ea Hydride e fokotsa sekhahla ho pH e sa nke lehlakore 'me e ba sethibelo ho feta ho pH e tlase.Phello e fapaneng ea viscosity ea solvent ho kcat/Km bakeng sa NAD(P)H e bonoa ka pH e sa nke lehlakore athe phello e tloaelehileng ea viscosity ea solvent e ile ea bonoa pH e tlase.Ka kopanelo, liphetho li bonts'a mokhoa o ikhethileng moo phetoho ea ho fokotsa sekhahla le pH-sensitive conformational e hlahang ho reductive half-reaction, e amang katleho ea lysine hydroxylation.
